In the spring and early summer coyotes become extremely territorial. That absolutely will not tolerate a canine of any kind anywhere near their dens. Normally coyotes are super skittish but when they are on their dens they have no fear. The purpose of the decoy dogs is to agitate them enough to bring the coyote in close enough to shoot. It usually starts out as a game of chase. Once the coyote commits and comes following the decoy dog in, (thinking it's going to kill the dog), we are waiting with a little surprise for them. It's really interesting because many times the coyotes absolutely know a human is there, but their hatred for canines overrides their normal desire to flee. It's sometimes unreal how close they will come to you knowing full well you are sitting there with a rifle in your hands. It is about the most intense form of coyote hunting I know of.
